This would also mean that an original numbers matching BS23 or BS27 'Cuda & original JS23 & JS27 R/T Challys - if you got the automatic and 383 you didn't get a Magnum or Super Commando engine, and I don't think there is an original owner out there that can say this is a fact.

I've never seen a 330hp engine in a 1970 R/T or 'Cuda?

All 'Cudas and all R/T's all had HiPo engines...4 speed or not. I think there is a hole in this answer...big time, and still room for lots of debate. I think this info you provided is false in these ways. IMO - what do you think, is there any truth in what I've stated, let's hear from someone that knows for sure. I knew this might be a hot topic of debate so don't take what I've said the wrong way. cool! that green chally vert you've got is bad [Edited by Moparts - Keep it clean] and you do know what you're talking about.
